“…This demonstrates that the seedling emergence test can be a good indicator for differentiating seed vigor. More vigorous seeds produce seedlings with higher potential when compared to less vigorous seeds (Cruz et al, 2021).…”

“…Similar behavior was observed for the species Anadenanthera colubrina (Vell.) Brenan, in which seeds in the early maturation stages had larger dimensions, with reductions at the final stages (Cruz et al, 2021). Likewise, the length, diameter, and thickness of Albizia niopoides (Spruce ex Benth.)…”

“…Considering the above, it is of utmost importance to identify the optimal time for collecting seeds with maximum physiological quality to improve their production (Cruz et al, 2021). In this sense, the present study aimed to analyze morphological and physiological changes during the maturation of C. tocantinum seeds to determine the optimal time for seed collection.…”

Studies on seed maturation directly contribute to obtaining seeds with a higher standard of physical, physiological, and sanitary quality. Thus, the aim of this study was to verify the morphological and physiological changes during the maturation of Cenostigma tocantinum Ducke seeds. The maturation stages were analyzed: I (293 days after anthesis - DAA), II (322 DAA), III (350 DAA), and IV (356 DAA) through visual, biometric analyses, and quantification of moisture content, dry mass, viability, and seed vigor. During the development of C. tocantinum seeds, changes in fruit coloration and an increase in fruit and seed length, width, and thickness were observed. In the initial stages, the seeds had a high moisture content, which decreased in the later stages. On the other hand, the dry mass of the seeds showed an inversely proportional behavior to the moisture content. Physiological variables performed better in stages III and IV, except for electrical conductivity. It can be concluded that C. tocantinum seeds showed superior physiological quality in stages III or IV, recommending the collection of seeds during these maturation periods.

“…The high seed moisture content (53.1 to 60.5%; Table 1), the low percentage of emergence (1 to 6%; Figure 2) and the lowest seedling emergence speed index (0.011 to 0.094% day -1 ; Table 2), referring to green fruits, indicate that the low vigor of seeds at this stage was due to physiological immaturity, as observed in Allophylus edulis (Kaiser et al, 2016), Dovyalis hebecarpa (Gardner) Warb. (Villa et al, 2019), Albizia hasslerii (Ristau et al, 2020), Anadenanthera colubrina (Cruz et al, 2021) and Physalis peruviana (Barroso et al, 2022).…”

Emergence of Coccoloba gigantifolia Melo, Cid Ferreira & Gribel seedlings as a function of raceme and fruit maturation

2023

Coccoloba gigantifolia fruits show uneven maturation within each raceme, which can affect the quality of the seeds. This study aimed to characterize racemes, fruits, and seeds, after harvest, and evaluate the physiological performance of the seeds as a function of the fruit maturation stage. After characterization, two experiments were set up. In the first, a completely randomized design was used, in a 4 (racemes) x 4 (fruit maturation stages: green, half-green, red, and purple) factorial scheme, with 4 replications. In the second, a randomized block design was adopted, in a 4 (fruit maturation stages) x 2 (with and without seed drying) factorial scheme, with 4 replications. Fruit maturation occurs progressively within each raceme, with fruits from completely green to completely purple in color existing at the same time. In propagation, preference should be given to harvesting racemes with a greater number of fruits in the half-green, red, and purple stages, since seeds from green fruits have low physiological quality. In addition to the variation in emergence as a function of fruit maturation, the seeds of the different racemes also showed different behaviors, which seems to be associated with different levels of seed dormancy.

O estudo avaliou o efeito de diferentes substratos na germinação de sementes de Handroanthus heptaphyllus (ipê-roxo). Realizado no viveiro florestal da Universidade Federal do Tocantins, o experimento utilizou doze tratamentos compostos por combinações de substratos como solo comercial, cama de aves, resíduos frigoríficos, cinza de caldeira e casca de arroz carbonizada. Apesar da variedade de substratos, a germinação das sementes ocorreu de forma consistente em todos os tratamentos, com valores acima de 92%. A velocidade de germinação foi mais influenciada pelos tratamentos T1, T2, T6, T7 e T10, que apresentaram as maiores médias, indicando que essas combinações proporcionaram condições mais favoráveis para o rápido desenvolvimento das plântulas. Por outro lado, o tratamento T9 registrou uma velocidade de germinação significativamente inferior, sugerindo que a proporção entre solo e cama de aves pode ter afetado negativamente o processo de germinação. A análise das correlações entre as variáveis de qualidade fisiológica das sementes indicou que a porcentagem de germinação está fortemente relacionada com à velocidade de germinação, enquanto o tempo médio de germinação mostrou uma correlação negativa, menos significativa. Esses resultados ressaltam a importância de escolher cuidadosamente os substratos para produção de mudasde ipê-roxo, visando garantir um crescimento saudável e uniforme das plantas.
